CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims priority to U.S. Provisional Application Ser. No. 62/253,867, filed on Nov. 11, 2015 and which is incorporated by reference herein in its entirety.

FIELD

The present disclosure relates generally to optical connection terminals for fiber optic communications networks, and more particularly to multi-port optical connection terminals for use as branch points in fiber optic communication networks.

BACKGROUND

Optical fiber is increasingly being used for a variety of applications, including broadband applications such as voice, video and data transmissions. As a result of this increasing demand, fiber optic networks typically include a large number of mid-span access locations at which one or more optical fibers are branched from a distribution cable. These mid-span access locations provide a branch point from the distribution cable and may lead to an end user, commonly referred to as a subscriber. Fiber optic networks which provide such access are commonly referred to as FTTX “fiber to the X” networks, with X indicating a delivery point such as a premises (i.e. FTTP).

Recently, multi-port optical connection terminals have been developed for interconnecting drop cables with a fiber optic distribution cable at a predetermined branch point in a fiber optic network between a mid-span access location on the distribution cable and a delivery point such as a subscriber premises. For example, U.S. Pat. No. 7,120,347, filed on Jan. 27, 2004 and entitled “Multi-port Optical Connection Terminal”, and U.S. Pat. No. 7,333,708, filed on Aug. 23, 2006 and entitled “Multi-port Optical Connection Terminal”, both of which are incorporated by reference herein in their entireties, discloses various such terminals. Utilizing such terminals, drop cables extending from a delivery point may be physically connected to the communications network at the branch point provided by such terminals as opposed to at the actual mid-span access location provided on the distribution cable. As a result, the terminal may be positioned at a more convenient location and a field technician may readily connect, disconnect or reconfigure the optical connections without the need for entering the closure at the mid-span access location.

However, while various such optical connection terminals have been developed, known terminals such as those described above suffer from various disadvantages. For example, stub cables are connected to the terminals to provide the connection to a distribution cable at a mid-span location. However, concerns exist with regard to the security of the stub cable connection. Accordingly, optical connection terminals that provide improved stub cable connection features are desired.

DETAILED DESCRIPTION

Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

The present disclosure is generally directed to optical connection terminals for fiber optic communications networks which provide improved stub cable connection. For example, the present disclosure provides embodiments of a multi-port optical connection terminal which includes a plurality of connector ports that receive optical connectors for interconnecting one or more pre-connectorized fiber optic drop cables to a distribution cable at a branch point in a fiber optic communications network. The various embodiments of the present disclosure may be applied in an optical “fiber-to-the-X” (FTTX) network. As used herein, the term “drop cable” includes a fiber optic cable comprising a cable sheath or jacket surrounding at least one flexible transport tube containing one or more optical fibers. As used herein, the term “distribution cable” includes both a main feeder cable, a distribution cable and/or a branch cable, and may be any type of fiber optic cable having a fiber count greater than that of an associated drop cable. In one example, the distribution cable may comprise at least one, and preferably, a plurality of flexible buffer tubes. As used herein, the term “optical fiber” includes all types of single mode and multi-mode light waveguides, including one or more bare optical fibers, loose-tube optical fibers, tight-buffered optical fibers, ribbonized optical fibers and/or any other embodiments of a medium for transmitting light signals. Pre-connectorized drop cables may be readily connected to and disconnected from the multi-port optical connection terminal, such as to adaptors disposed within the connector ports thereof, thus eliminating the need for entering the multi-port terminal and splicing the optical fibers of the drop cables to optical fibers of a stub cable, as described herein.

The fiber optic drop cables may be optically connected, i.e. via the terminal, to optical fibers of a communications network, such as within a conventional outside plant closure, such as a local convergence cabinet (LCC), a pedestal, a network access point (NAP) closure, or a network interface device (NID). In some embodiments, the fiber optic drop cables extend from a NID located at a subscriber premises and are optically connected through the multi-port optical connection terminal to optical fibers of a stub cable at a branch point in the network. In turn, the optical fibers of the stub cable are optically connected to respective optical fibers of the communications network at a mid-span access location provided on a distribution cable. The mid-span access location may be provided at an aerial closure, a buried closure (also referred to as a below-grade closure) or an above ground telecommunications cabinet, terminal or pedestal. Likewise, the multi-port optical connection terminal may be provided at an aerial location, such as mounted to an aerial strand between telephone poles or mounted on a telephone pole, at a buried location, such as within a hand-hole or below grade vault, or at an above-ground location, such as within a cabinet, terminal, pedestal or above grade vault. Optical connection terminals in accordance with the present disclosure may thus facilitate the deployment of a FTTX communications network.

The multi-port optical connection terminal provides an accessible interconnection terminal for readily connecting, disconnecting or reconfiguring drop cables in the optical network, and in particular, for interconnecting drop cables with a distribution cable. As used herein, the term “interconnecting” describes the connection of a drop cable to a distribution cable through an optical connection terminal in accordance with the present disclosure. In other words, such terminals are quick-connect terminals for connecting drop cables to a distribution cable of an optical communications network at a location other than the actual mid-span access location provided on the distribution cable.

A stub cable of the multi-port optical connection terminal may be connected to the fiber optic distribution cable by any suitable means. The drop cables may be connected to the stub cable via a terminal, thus connecting the drop cables to the distribution cable. In accordance with the present disclosure, the stub cable may be securely connected to the optical connection terminal. In particular, a stub cable connector of the terminal may be utilized to connect a stub cable to the terminal. The connector and terminal may include various advantageous features for securely connecting the stub cable to the connector and the connector to the housing of the terminal.

Referring now to FIG. 1, a portion of a known fiber optic communications network 10 which includes a fiber optic distribution cable 12 and at least one multi-port optical connection terminal 100 constructed in accordance with the present disclosure is shown. At least one (as shown), and preferably, a plurality of mid-span access locations are provided along the length of the distribution cable 12. The mid-span access location may be enclosed and protected from exposure to the environment by a conventional closure 14. In a preferred embodiment, the fiber optic communications network 10 comprises a fiber optic distribution cable 12 having a plurality of mid-span access locations at branch points spaced along the length of the distribution cable, each providing access to at least one, and preferably, a plurality of optical fibers 18 of the fiber optic network. Thus, the distribution cable 12 provides multiple locations for joining a stub cable 24 of at least one multi-port optical connection terminal 100 to the distribution cable at each mid-span access location.

In the exemplary fiber optic network 10, pre-terminated optical fibers 18 of the distribution cable 12 provided at the mid-span access location are routed out of the distribution cable via an optical fiber transition element 20 and into corresponding hollow protective tubes 22. The optical fiber transition element 20 may include any structure that permits the pre-terminated optical fibers 18 to transition from the distribution cable 12 without excessive stress, strain or bending. The protective tubes 22 containing optical fibers 18 are routed into one or more splice trays 15, and the ends of the optical fibers 18 are spliced to respective optical fibers of a stub cable 24 extending from a multi-port optical connection terminal 100. The optical fibers of the stub cable 24 may enter the closure 14 through a suitable cable port 26 provided through an exterior wall, for example an end wall, of the closure 14. The stub cable 24 includes at least one, and preferably a plurality of optical fibers disposed within a protective cable sheath. The stub cable 24 may, for example, be any known fiber optic cable comprising at least one optical fiber and having a fiber count equal to or greater than that of a drop cable 16 to be connected to the multi-port optical connection terminal 100 and equal to or less than that of the distribution cable 12. The stub cable 24 may include a tubular body, such as, but not limited to, a buffer tube, a monotube or a tube formed from a water-swellable tape. In preferred embodiments, the stub cable 24 is flexible, easy to route and has no preferential bend.

The stub cable 24 extends from the closure 14 into the multi-port optical connection terminal 100 through a stub cable port 118 provided through an exterior wall of the multi-port terminal. The optical fibers of the stub cable 24 within the multi-port optical connection terminal 100 may be pre-connectorized, and the optical connectors are each inserted into a connector adapter seated in one of the connector ports 124 provided through an exterior wall of the terminal. One or more pre-connectorized drop cables 16 are then interconnected with the connectorized optical fibers of the stub cable 24 by inserting the pre-connectorized ends of the drop cables 16 into the adapters seated in the connector ports 124 from the exterior of the multi-port optical connection terminal 100. A stub cable port 118 of the multi-port optical connection terminal 100 receives the stub cable 24 therethrough via a stub cable connector as discussed herein, and the connector adapters disposed in the connector ports 124 receive the pre-connectorized optical fibers of the stub cable 24 and the connectorized ends of the drop cables 16. The drop cables 16 include at least one single mode or multimode optical fiber of any type optically connected to a single fiber or multi-fiber optical connector in a conventional manner. The other ends of the drop cables 16 are optically connected to respective optical fibers of the communications network within an outside plant connection terminal 28 at a delivery point, such as an outside plant network access point (NAP) closure, local convergence cabinet (LCC), terminal, pedestal or network interface device (NID). As shown, one or more stub cables 24 extends from the closure 14 to a multi-port optical connection terminal 100 positioned at a distance from the mid-span access location, such as a telephone pole, hand-hole, vault or pedestal (not shown) in the fiber optic network 10. Each drop cable 16 extends from a multi-port optical connection terminal 100 to an outside plant connection terminal 28 located at a delivery point such as a subscriber premises.

Referring now to FIGS. 2-14, exemplary embodiments of optical terminals 100 and various components thereof in accordance with the present disclosure are provided. As discussed, multi-port optical connection terminals 100 in accordance with the present disclosure permit one or more pre-connectorized fiber optic drop cables 16 to be readily interconnected with optical fibers of distribution cable 12 at a mid-span access location provided along the length of the distribution cable 12. Further, such multi-port optical connection terminals 100 provide a convenient connection point for a field technician to initially install and subsequently reconfigure the optical connections between the various drop cables 16 and the connector ports 124 provided on the multi-port terminal 100. Further, multi-port optical connection terminals 100 in accordance with the present disclosure advantageously include improved apparatus for securely connecting the stub cable 24 to the terminal. Such features as discussed herein advantageously enhance the terminal performance and limit mechanical stress during field installation.

As shown, a terminal 100 in accordance with the present disclosure may include a housing which may, for example, be formed from a base 152 and a cover 154. The base 152 and cover 154 may be formed from suitable materials, which may for example be lightweight and rigid. For example, suitable polymers or metals may be utilized.

Base 152 may include an exterior wall 160 which may define an interior cavity of the base 152. Further, a plurality of connector ports 124 may extend through the exterior wall 160 and provide access to the interior cavity. For example, the exterior wall 160 may include a first end wall 162, a second opposing end wall 164 which is opposite the first end wall 162 along a longitudinal axis of the terminal 100, a first sidewall 166, and a second opposing sidewall 168 which is opposite the first sidewall 166 along a lateral axis of the terminal 100. The sidewalls and end walls may, for example, generally form an outer perimeter of the base 152.

The exterior wall 160 may further include one or more angled surfaces 169, which may for example, each extend at an angle to a plane defined by the lateral and longitudinal axes of the terminal 100. In these embodiments, the connector ports 124 may be defined in the angled surfaces 169. For example, one or more connector ports 124 may be defined in each angled surface 169 as shown. Alternatively, other suitable surfaces may be provided between the sidewalls and end walls of the exterior wall 160, and the connector ports 124 may extend through one or more of these surfaces.

As illustrated, in exemplary embodiments the terminal 100 may include a plurality of connector adaptors 180. Each adaptor 180 may extend through one of the plurality of connector ports 124. The connector adaptors 180 may facilitate the connection of optical fibers from stub cable 24 to optical fibers of the drop cables 16. For example, as discussed, ends of the stub cable 24 optical fibers may be connectorized. Each such connector may be coupled to an adaptor 180 on the interior cavity side of the adaptor 180, i.e. the side of the adaptor 180 that is disposed within the interior cavity 156. Further, ends of the drop cable 16 optical fibers may be connectorized. Each such connector may be coupled to an adaptor 180 on the exterior cavity side of the adaptor 180. The adaptor 180 may thus connect the connectors and optical fibers to provide optical communication between the stub cable 24 and each drop cable 16.

The optical fiber connectors as discussed herein may be any suitable commercially available connectors such as, for example, SC, LC, FC, ST, SC/DC, MT-RJ, MTP and/or MPO connectors.

The cover 154 may be connected to the base 152. Cover 154 may include an exterior wall which may define an interior cavity of the cover 154. An interior cavity 156 may thus collectively be defined between the base 152 and the cover 154 by the interior cavit(ies) of the base 152 and/or cover 154. The interior cavity 156 may, in some embodiments, generally be utilized for housing fiber optic hardware, such as adapters, optical fiber routing guides, fiber hubs, splitters, etc.

The exterior wall of the cover 154 may include a first end wall 172, a second opposing end wall 174 which is opposite the first end wall 172 along a longitudinal axis of the terminal 100, a first sidewall 176, and a second opposing sidewall 178 which is opposite the first sidewall 176 along a lateral axis of the terminal 100. The sidewalls and end walls may, for example, generally form an outer perimeter of the cover 154. Cover 154, such as the exterior wall thereof, may further include a bottom panel 170. The bottom panel 170 may extend between the first and second sidewalls 176, 178 along the lateral axis and between the first and second end walls 172, 170 along the longitudinal axis.

Referring now in particular to FIGS. 5-8, 13 and 14, an exterior channel 190 may be defined in the bottom panel 170. The exterior channel 190 may thus be a recessed or depressed portion of the bottom panel 170 as shown. As discussed herein, a stub cable connector 200 may be positionable such that at least a portion of the connector 200 is disposed within the exterior channel 190. Further, an outer surface of the connector 200 (i.e. a cover panel thereof as discussed herein) may, when the connector 200 is seated in the exterior channel 190, be flush with the bottom panel 170 (i.e. the outermost portion of the surface of the bottom panel 170 not forming the exterior channel 190).

In exemplary embodiments as shown, the exterior channel 190 may extend longitudinally. For example, an entrance 192 to the exterior channel 190 may be defined underneath the end wall 172 as shown or end wall 174. Alternatively, however, the exterior channel 190 may extend laterally or in another suitable direction. For example, entrance 192 may be defined underneath the sidewall 176 or sidewall 178.

Further, a stub cable port 118 may be defined in the bottom panel 170, such as within the exterior channel 190, and may provide access to the interior cavity 156. When the stub cable connector 200 is positioned in the exterior channel 190, a portion of the stub cable connector 200 may extend through the stub cable port 118 and into the interior cavity 156.

Referring now in particular to FIGS. 5-14, embodiments of a stub cable connector 200 in accordance with the present disclosure are provided. Stub cable connector 200 may include a main body 202 and a connector body 204, and as discussed may be positionable at least partially within the exterior channel 190. In particular, the connector 200 may be positionable such that the main body 202 (such as a portion thereof) is within the exterior channel 190 and the connector body 204 extends through the stub cable port 118 and into the interior cavity 156.

Main body 202 and connector body 204 may each extend along a longitudinal axis 203, 205, respectively. The longitudinal axis 205 of the connector body 204 may be at an angle to the longitudinal axis 203 of the main body 202. For example, in exemplary embodiments, longitudinal axis 205 may be perpendicular to the longitudinal axis 203. Accordingly, in exemplary embodiments when positioned at least partially within the exterior channel 190, the main body 202 and longitudinal axis 203 thereof may extend along the longitudinal axis of the terminal 100 and the connector body 204 may extend perpendicular to the longitudinal axis and lateral axis of the terminal 100.

The main body 202 may define an interior channel 206 that extends therethrough. When a stub cable 24 is connected to the stub cable connector 200, a portion of the stub cable 24 may thus be disposed within the interior channel 210. The connector body 204 may define an interior passage 208 that extends therethrough and is in communication with the interior channel 206. Optical fibers 300 of the stub cable 24 may extend from the interior channel 206 through the interior passage 208. Further, when the connector 200 is positioned at least partially within the exterior channel 190 and the connector body 204 thus extends through the stub cable port 118, the optical fibers 300 may exit the connector body 204 in the interior cavity 156. Within the interior cavity 156, connectorized ends of the optical fibers 300, such as connectors thereof, may be connected to the adaptors 180 (i.e. the portions of the adaptors 180 within the interior cavity 156) to provide optical communication between the stub cable 24 and each drop cable 16 (i.e. the connectorized optical fibers thereof).

To securely connect the stub cable connector 200 to the stub cable 24, retainers 210 may be provided in the main body 202. For example, one or more retainers 210 may extend into the interior channel 206 to securely hold the stub cable 24. In exemplary embodiments as shown, the retainers 210 are sawteeth sidewalls, i.e. sawteeth shaped portions of the interior sidewalls defining the interior channel 206. The sawteeth sidewalls may contact and in some embodiments protrude into an outer sheath 302 of the stub cable 24, thus securely grasping and holding the stub cable 24 within the interior channel 206.

Additionally or alternatively, an adhesive may be provided in the interior channel 206. Such adhesive may be provided between the stub cable 24 and the interior sidewall(s) defining the interior channel 206, and may adhere the stub cable 24 to the sidewall(s), thus securing the connector 200 to the stub cable 24.

Stub cable connector 200 may further include protrusions 212 which extend into the interior channel 206 and divide the interior channel 206 into sub-compartments. The protrusions 212 may act as restrictions on the cross-sectional size of the interior channel 206 in order to prevent portions of the stub cable 24 from extending therethrough. For example, an outer sheath 302 may be prevented from extending through the protrusions 212 due to the relatively narrower opening defined by the protrusions 212, but the tubular body 304, such as the buffer tube, and optical fibers 300 therein may be allowed past the protrusions 212.

Stub cable connector 200 may further include a furcation block 214 through which the optical fibers 300 may pass. The furcation block 214 may be disposed within the interior channel 206, and may assist in separating the optical fibers 300 as the fibers emerge from the tubular body 304, as shown. The optical fibers 300 may then extend from the furcation block 214 and interior channel 206 into the interior passage 208, and from the interior passage 208 into the interior cavity 156 as discussed.

Stub cable connector 200 may further include a cover panel 220. The cover panel 220 may be connected, such as hingedly connected, to the main body 202. Cover panel 220 may provide access to the interior channel 206, as shown, and may protect and secure the stub cable 24 and optical fibers 300 thereof when in the closed position. In exemplary embodiments, an outer surface of the cover panel 220 is flush with the bottom panel 180, as discussed above, when the stub cable connector 200 when the stub cable connector 200 is properly seated in the exterior channel 190. It should be noted that, in alternative embodiments, no cover panel 220 may be necessary and the interior channel 206 may be defined in the main body 202 such that a portion of the main body 202 forms an integral cover.

As discussed, cover panel 220 may be hingedly connected to the main body 202. For example, and referring to FIGS. 13 and 14, in some exemplary embodiments, one or more, such as in exemplary embodiments a pair, of hinge arms 240 may extend from cover panel 220. Each hinge arm 240 may further include a distal end 242 opposite the connection of the hinge arm 240 to the cover panel 220. A pivot point 244 may be defined by the distal end 242, and the hinge arm 240 and cover panel 220 may be rotatable towards and away from the main body 202 about such pivot point 244 (perpendicularly to axes 203 and 205). Distal end 242 may further protrude inwardly, and may fit within a depression 246 defined in the main body 202, such as the outer surface thereof. Such connection between the distal end 242 and depression 246 positions the cover panel 220 relative to the main body 202 and facilitates rotation of the cover panel 220 relative to the main body 202.

The hinge arms 240 and distal ends 242 thereof may further assist with securing the stub cable connector 200 in the exterior channel 190. For example, as shown in FIGS. 6, 7 and 14, the stub cable connector 200 may be rotatable into and out of a fully seated position in the exterior channel 190. As shown in FIGS. 13 and 14, protrusions, such as hook-shaped protrusions 250 as shown, may extend into the exterior channel 190 and contact the hinge arms 240 and distal ends 242 to catch the hinge arms 240 and thus the stub cable connector 200. The distal ends 242 may further seat within depressions 252 defined in the walls defining the exterior channel 190. This may position the stub cable connector 200 partially or fully within the exterior channel 190, thus securing the stub cable connector 200 to the cover 154 and facilitating rotation thereof into the fully seated position in the exterior channel 190.

Stub cable connector 200 may further include a boot 222 which may be connected to the main body 202, such as opposite the connector body 204. The stub cable 24 may extend through the boot 222 prior to entering the main body 202, as shown. Boot 222 may protect the portion of the stub cable 24 protruding from the main body 202 at that end of the main body 202 and further secure the stub cable 24 to the connector 200.

To secure the connector 200 to the housing of the terminal 100, a connection may be provided which affirmatively couples the connector 200 to the housing. For example, in exemplary embodiments as shown, the connector body 204 may be threaded. External threads 230 may thus be provided on the connector body 204. When the connector 200 is properly seated in the exterior channel 190, the threads 230 may extend through the stub cable port 118 such that at least a portion of the threads are disposed in the interior cavity 156. In further exemplary embodiments, a threaded nut 232 (which may include internal threads 234) may be provided. The threaded nut 232 may be positionable within the interior cavity 156, and may threadably engage the connector body 204 in the interior cavity 156. Such threaded engagement connects the connector 200 to the cover 154 and housing generally, thus securing the stub cable 24 to the terminal 100.

Accordingly, stub cable connectors 200, the positioning of the stub cable port 118, and terminals 100 in accordance with the present disclosure provide a variety of advantages, including ensuring that the stub cable 24 is securely connected to the terminal 100. For example, such apparatus advantageously allows for the stub cable 24 to be quickly and efficiently removed and replaced, i.e. in the field. Optical fibers 300 of the stub cable 24 can be easily routed into the terminal housing through the stub cable connector 200, enhancing terminal 100 performance and reducing mechanical stress during field installation.
